Abstract (en)
[origin: WO2023019434A1] A chuck (10) for use with a power driver having a rotatable drive spindle. The chuck may include a sleeve (60) comprising a sleeve tightening surface (62) that may be configured to engage with a nut tightening surface (502) to tighten a nut (50) when the sleeve is rotated into a tightening position. With the sleeve disposed in a sleeve locked position, a click pawl (732) may be engaged with a click stopping edge (771) of one of the plurality of click teeth (756) to inhibit rotation of the nut in a first rotational direction to loosen the nut. A lock pawl (722) may also be engaged with a lock stopping edge (761) of one of the plurality of lock teeth (755) to inhibit rotation of the sleeve in a second rotational direction due to the inertia in the sleeve that would tend to further tighten the nut.
